CAKE-COATING MACHINE.

Specication of Letters Patent.

Patented Feb. 22, 1916.

Application led February 21, 19M.` Serial No. 820,168.

To all whom it may concern: v n

Be it known that I, PEMBROKE D. HAMON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Cake-Coating Machines, of which the following is a specification.

The object of my invention is to provide improved mechanism for applying coating or icing materials to small cakes, and it is moreparticularly'directed to means for simultaneously applying a plurality of materials.

The machine to which my present improvements have been applied may be substantially similar to that illustrated in my prior Patent, N o. 1,036,108, Aug. 20, 1912.

M present improvements relate more particularly to the means for effecting delivery of the coating material from the reings,

, perspective views frames of the machine on w Va portion of the ceptacles containing the same, such delivery taking place at a common point where portions of the separate bodies of coating materials may be discharged axially wi respect to each other, from nozzles or oriices in a fixed head.

An important object of my to provide means for positively se aratmg coating material rom the main body of the same, from which smaller body the portion subsequently ejected u on the cakes is taken. When the action of ischarging or delivering the coating material is completed, the retraction of the means effecting the same produces a quick, sharp separation of the coating material within the nozzles from that on the cakes.

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawin which:

Figure 1, is a side elevation of sufficient of a cake coating machine to illustrate my present invention; Fig. 2, is a sectional elevation on the line 2.2, Fig. 3; Fig. 3, is an enlarged plan view of my im roved mechanism for discharging the coating material; Figs. 4, 5, 6 and 7, are diagrammatic views of a part of the mechanism shown in Fig. 2, illustrating such mechanism in different positions; Fig 8 is a section on the line a-s, Fig. e, and ings 9 and 1o, are detailed illustrating details of my im roved mechanism.

n the drawings, 1, 1, re

invention is resent the side ch are mounted a series of gether, as hereinafter described; the main driving shaft 2 carrying a driving pulley 3. Mounted on said shaft, between the side frames, is a pinion 4, which meshes with a gear wheel 5, mounted on a shaft 6, paralleling the shaft 2. The pinion 4 also meshes with a pinion 7 mounted on a shaft 8, also parallehng the shafts 2 and 6, which pinion in turn meshes with a gear wheel 9 mounted on a shaft 10. The shaft 6 also carries a gear wheel 11 meshing with a gear wheel 12 on a shaft 13, and the gear wheel 12 meshes with a gear wheel 14 on a shaft 15; such elements being constructed and arranged all as hereinafter set forth. To avoid confusion, the teeth of the several gear wheels have been omitted.

The cakes to be coated may be laced on a table 20, `and they are moved a ong step by step by suitable conveying mechanism 20, being transferred from said table to an endless belt conveyer 21, by a pushing or centering barV 22 operated by suitable mechanism, properly tlmed with respect to the cake conveying means, as more full described in my prior patent before re erred to. The bar 22 serves to transfer the cakes from the table 20 to the conveyer belt 21, and so arranges the cakes that on the next intermittent movement of the conveyer belt the cakes will be brought to a position beneath the center of a box or receptacle 23, from which a coating of jelly or other material may be deposited u on the cakes. At the end of the next or third movement of the conveyer belt 21, the cakes are brought to a central position beneath another receptacle or hopper 25, and from this hopper the cakes receive a double deposit, axially delivered, which may consist of separate bodies of chocolate and marshmallow, or any other material desired.

The hopper 25 comprises an upper removable section 26, and a lower section 27 fixed to the side frames of the machine. lower section 27 consists of two end frames 30-30, suitablyV spaced apart by bottom and side members 31 and 32, and such lower section has a" artition 33 extending the full length thereo dividing the same into separate compartments 28 and 29. The removable section 26 also has a partition 34 dividing it into separate compartments 35 and 36, When the section 26 of the hopper is placed in proper position, the partition 34 shafts suitably geared toi thereof rests upon the partition 33 of the section 27, and the compartments 35 and 36 register with the com artments 28 and 29, thereby forming sing e compartments, respectively.

The bottom plate 31 of the section 27 is provided with an opening into which the partition 33 extends and forms the dividin wall of a pair of slots 38 extending the fu length of said plate, in which slots are mounted a pair of butterfly valves 39. These valves may be suitably operated simultaneously, to permit or to out oil' flow of material from the compartments 28 and 29 to the nozzle carrying member 40.

Slidably mounted in the lower part of the compartments 28 and 29, and resting on the bottom plate 31, is a pair of bars 41 which act as plungers, being moved back and forth within chambers 28 and 29" formed between a pair of flat, blade-like, cut-off bars 42, (operating directly above the plunger bars 41,), and the bottom plate 31; said bars 42 also acting as knives to cut through the coating material and together as partitions to separate the material in the chambers 28 and 29a from the main body of material in the compartments 28 and 29.

The plunger bars 41 do not extend the full length of the compartments 28 and 29; filler plates 43 being provided between the ends thereof and the end plates 30 of the hopper. The bars or blades 42 extend the full length of the compartments 28 and 29, however; a guideway being provided for the same between the top of the filler plates 43 and the lower edge of extensions 44 of end plates 45 of the removable section 26.

As shown in Fig. 2, a deposit of coating material has been placed upon the cake w, which has previously been raised by the conveyer belt, the valves 39 being open, the knife bars 42 are in contact with the partition 33 and the plunger bars 41 in their extreme inward position having forced the material through the slots 38 past the valves 39. In the next movement shown in Fig. 4, the plunger bars 41 have started to move outward (in the direction of the arrows) causing suction in the chambers 28a and 29, thereby drawing the material up through the slots 38, breaking the same from the cakes. which at this point of the operation are lowered by the conveyer belt 21, in a manner hereinafter described, simultaneously with the commencement of the out ward movement of the plunger bars 41. During this part of the outward movement of the plun ers 41, the knife bars 42 and the butterfly va ves 39 remain stationary.

Upon a continued movement of the plunger 41 in the direction of the arrows, (Fig. 5) the valves 39 are turned to the closed 4position and the knife bars 42 receive a quick outward movement to the position shown in be varied by Fig. 5. This causes the plungers 41 in their outward movement, to draw a new c arge of material from the compartments 28 and 29 into the chambers 28 and 29a; the movement of the plungers continuin until the position shown in Fig. 6 is reac ed. During this period, a row of coated cakes has been moved away from the nozzle member 40 and a fresh row of uncoated cakes has been brought under the said nozzle member by the conveyer belt 21- the cakes being raised to a position ready for coatin by suitable mechanism, hereinafter described, controlled by the shaft 13. The next operation is to impart a quick inward movement to the knife bars 42, separating the material in the chambers 28.* and 29 from the bulk of material in compartments 28 and 29. At the same time the valves 39 are opened (Fig. 7), and the plungers 4l continue to move in the direction of the arrows until the position shown in Fig. 2, is again reached, oompleting the deposit of material upon the line of cakes positioned under the nozzles in the member 40. f

Movement is imparted to the plunger bars 41 by a pair of suitably sha ed cams 50 and 50, one of which is mounted3 on the shaft 6; the other being mounted on the shaft l0. A pair of adjustable levers 51 and 51l1 are pivoted to the frame l of the machine at 52 and 521. The levers 51 and 51a carry rollers 53 and 53- which ride on the periphery of the cams 50 and 50, being held in Contact therewith by means of weights 55 and 55a carried by the outer end of said levers. The levers 51 and 51a are slotted at 56 and 56al for the reception of internally threaded blocks 57 and 57a; said blocks having lugs 58 and 58 to which are pivoted links 59 and 59a; the opposite ends of said links being connected to levers 60 and 60a carried by the ends of rock shafts 61 and 61a. Each rock shaft 61 and 61a also carries a pair of levers 62 and 62a; the lower ends of which are connected to links 63 and 63, and the latter connected to rods 64 and 64 slidably mounted in the side walls 32 of the section 27. The inner end of said rods 64 and 64L are provided with heads 65 and 65a arranged to fit openings 66 in the bars 41; said bars having slots 67 to accommodate the reduced portions 68 and 68a of the rods 64 and 64. The peculiar shape of the peripher of the cams 50 and 50, which are rotatedY by the beforementioned gearing, causes the plungers 41 to be reciprocated. The amount of movement imparted to said plungers may operating the hand wheels 70 and 70I1 carried by the levers 51 and 51, thereby turning the screws 71 and 71 and movingr the nuts 57 andv 57EL toward or away from the pivotal connections of said levers. The movement of the plungers 41 may be decreased by moving the nut 57 or 57 of the valves 39.

arrasar toward the pivotal connections 52 or 52 until said nuts are directly over the said connections, at which time the plungers 41 will receive no movement. To give the plungers 41 their full movement, the nuts 57 and 57 are moved to the extreme ends of the slots 56 and 56a in the levers 51 and 51,

Movement is imparted to the knife bars 42 and butterfly valves 39 through the medium of a pair of cams 80 and 8l on the shaft 15. A rod 82 connected at its upper end to a lever 83 mounted on a rock shaft 84, is provided with a head 85 at its lower end. This head 85 carries a pair of rollers 86 and 87 in contact with the cams 80 and 81, respectively; said cams raising and lowering the rod. 82 to give the knife bars 42 and valves 39 their desired movements at the proper time. The lever 83 has an extension 88 connected by a link 89 to a lever 90 carried by the outer end ofone The valves 39 are also provided with meshing pinions 91, so that movement imparted to one of said valves will be communicated directly to the other. The rock shaft 84 also carries a lever 92 connected by a link 93 to a lever 95 mounted on another rock shaft 96. The rock shafts 84 and 96 each carry a pair of levers 97, having slots 98 through which a rod 99 paes; said rod connecting a pair of slide rods 100 having heads 101 adapted to notches or slots 102 in the bars 42. When the shaft 15 is rotated, it gives the proper movement to the knife bars 42 through the series of cams, links, shafts and levers just described. The rock shafts 6l, 61, 84 and 96 may be mounted in bearings formed in 'an extension of the end plates 30 of the lower section 27 of the hopper 25,`

For the purpose of cleaning the hopper 25 and its internal operating parts, the upper section 26 is made removable, for which purpose the lower section 27 is pro vided with bolts 105 pivoted thereto at 106; the' bolts 105 passing through slots 107 formed in the end of the upper section 26 and having thumb nuts 108. The nuts 108 may be backed off and the bolts 105 thrown out of the slots 107 to permit removal of said upper section 26. The portion 44 being an integral part of the upper section also lifted from the top of the knife plates 42. The knife bars 42 can then be removed by grasping the lugs 109; the heads 101 of the rods 100 sliding out ofthe slots 102 in said bars. The plunger bars 41 can then be removed in like manner, and the entire internal portion of the ho per 25 is ready `:for cleansing in any suitab e manner. The partition 34 may be removed from the upper section 26, :for the purpose of filling said--section 26 with but one class of coatmg material; said partition being held in grooves formed in the end plates 45.

In order to raise the cakes to a position to be coated, the shaft 13 is provided with a cam 110, operating against a roller 111, carried by a head 112 mounted o n the lower end of a rod 113, the upper end of which is adjustably pivoted to a lever 114. The said lever is mounted on one end of a shaft 115, journaled in the side frames of the machine, and carries a pair of levers 116, the outer ends of which operate on the under side of a bar 117 extending the full width of the machine, over which the belt conveyer 21 moves to raise said bar 117. The bar 117 is adapted to slide vertically in grooves 118 formed in the side frames 1, 1,

of the machine. The shaft 115 carries at the end opposite the lever 114 a weight 119 for the purpose of automatically lowering the bar 117 when the roller 111 is in contact with the low side of the cam 110.
